Clinical Significance
Successful immediate implantation in debrided infected sockets is largely dependent on complete removal of all contaminated tissues, controlled regeneration of
Immediate implant placement reduces treatment time, improves the esthetic outcome, increases the patient’s comfort during healing, and has been highly predictable with high rates of success when no periapical lesions are present. Immediate placement also maintains the horizontal and vertical dimensions of osseous tissues and retains the angle of implants in line with preexisting natural teeth. Some studies indicate that periradicular infection is less common in immediate implants if the
The noninfected sites served as the control group (CG), and the infected but treated sites were the test group (TG). The infected sites were managed with debridement, curettage, cleaning with 90% hydrogen peroxide, irradiation with yttrium-scandium-gallium-garnet lasers, and chlorhexidine rinses, along with GBR and antibiotic coverage. Pain, occlusion, prosthesis mobility, and the fulfillment of success criteria were analyzed, along with successful osseointegration after 12, 24, and 36 months (
No significant difference was noted between the survival rates of the TG and CG implants. TG implants had a survival rate of 100% after 12 and 24 months and 94.44% after 36 months. CG implants had a survival rate of 100% at all three evaluation points.
The PD did not change significantly from baseline until 36 months in either group. Mean mPI scores were also statistically similar at baseline and after 24 and 36 months. Lower values were noted for the TG implants than the CG implants after 12
The success rates for implants placed in infected but treated and noninfected sites were comparable. Maintenance and health of the peri-implant soft and hard tissues was similar between the test and control groups. Corroboration of these positive findings will require clinical trials that last longer than 36 months.
